'I have three cats and my helper takes care of them when I'm away. Cats are more independent than dogs, they may even be happier without people around, whereas dogs are attention-seeking. About 10 years ago, I kept a stray dog that followed me home. When I was away working I asked my parents to visit it when they had time, but the security guard told me it was howling at nights. I felt really sorry, so I gave him to a loving family who could play with him every day.'
